Title:
BIPOLAR BATTERY WITH PROTON AND HYDROXIDE ION CONDUCTING POLYMER BASED SEPARATOR
Document Type and Number:
WIPO Patent Application WO/2022/239204
Kind Code:
A1
Abstract:
Provided are bipolar batteries that include a stacked plurality of cells. Two or more of the cells include a cathode, an anode, a proton or hydroxide ion conducting polymer separator between the cathode and said anode, wherein in some aspects the separator includes or alone acts as a proton or hydroxide conducting electrolyte, and a bipolar metallic plate associated with the anode or the cathode. The cells optionally include and electrolyte that includes a polymer capable of conducting a proton or a hydroxide ion. The separator may in the form of a film and is optionally not bonded to either the anode or the cathode, or may be in the form of a coating on the anode, the cathode, or any combination thereof.
